GANG-PLOW.

Specification of Letters Patent.

Patented Feb. 27, 1 906.

Application filed April 29, 1905. Serial No. 258.006.

to which it appertains to make and use the same.

My invention relates to gang-plows, and has for its object to improve the same in point of simplicity, eliiciency, and ease of m anipui ation. I

To the above ends my invention consists of the novel device and combination of devices hereinafter described, and dclined in the claims.

In the accompanying drawingsis illustrated myinvention, like characters indicating like parts throughout both views.

Figure 1 is a plan view showing the improved plow; and Fig. 2 is a side elevation with some parts broken away, showing the plow illustrated in Fig. 1.

The numeral 1 indicates an approximately triangular truck-frame, the side and forward portions of which are supported by a pair of caster-wheels 2, and a rear side portion. of which is supported by a steering-whecl 23, mounted in a fork 4, which is journalcd in a hearing 5 on said platform 1 and is provided with a latcrally-projecting arm 6.

At the forward central portion of the truckframe 1 is a prongcd couplirig-bracket 7, to which is pivoted a draft-beam 8. One end of this pivoted draft-beam b is connected to the arm 6 of the wheel-yoke 4. by a long diago nally-extemled rod 9.

This gang-plow is especially designed and intended to be drawn by a tractioii-cngine,

and, as shown, the beam 3 provided at its ends with hooks 10, which arc coupled to links 11. on the rear portion of thefiame 12 ,of the traction-engine, which frame is indicated only in part and in diagram in Fig. 1. By means of the steering connections just doscribod the steering-wheel 3 will be oscillated in the proper direction to cause the truck to turn curves and follow in the path of the trzwtion-engine.

Rigidly secured to and depended from the forward portion of the t-ruclcl'rame l, at the sides thereof, a pair of laterally-spaced legs 13, that terminate a considerable distance I i l 1 l E l lliroiigh which long bars or rods 2? freely tel- I The bars 22 at their lower rear- 90 above the ground. Extending transversely ol the machine and rigidly but ad plstably secured to the legs 13 1s a dragbar 14, the ends of which, as shown, are adjustablysecured to said legs by bolts or pins 15, passed therethrough and through perforations 16 in said legs.

The plows 17 are arranged in. a transversely-spaced series located successively one at the rear of the other from left side toward the right side of the machine. These plows 17 are independently connected by chains 18 or similar connection to the transverse bar 14:. spaced perforations l4, and said chains 18 at their forward ends are provided with bifurcated coupling-links it), th ough which said perforations l4? pins or bolts 19 are passed to adjustably secure the said plow connections to the drag-bar lat. The several plows are independently held in upright operative positions by novel devices which permit said plows to freely move laterally to adapt themselves to the proper cut or width of furrow and to move vertically into and out of operative positions. Each such device comprises a short vertical post or pedestal 20, which is swiveled in the truck frame 1 and to the upper end of which is pivoted an elongated head 21. These heads 21 are for pivotal movements in a vertical plane and are provided with longitudinal pertorations cscopc. war( 1 ly-proj ccting ends are pivot ally attached one to each plow-beam.

Secured at its ends to brackets 23 on the truck-frame 1 and extending diagonally of the machine over the rear portions of the plow r, 5

is a lorg rod 0" shaft24, upon which is mounted a plurality of lifting-levers 25. ()no of 'thcsc liftingdevcrs 25 is provided for each plow, and each lever has a latch 26, that cooperates with the notched disk 27, rigidly sercc cured on the fixed shaft 24, a .d at their pivoted duds the lovers 25 arc provided with sheaves 28. To each plow-beam is attached. a lifting-chain 2t), thc upper end of which runs upon and is attached to sheave 28 of the corresponding lifting-lever By means of the lifting levers and connections described it is evident that the plows may be independently raised and lowered and that the said plows are free for all these movements which I rc are necessary in the plowing action and ihat the said plows by means of thc steadrmg The said bar HE is provided with closely- 7o tially as escribed.

bars or rods 22 and connections are held uprightthat is, are prevented from tilting over or rocking out of their proper operative positions. It is also evident that the depth of out which the plows will make may be regulated by vertical adjustments of the dragbar 14.

The plows described are extremely simple, are eiiicient for representing the view, and may be very easily manipulated. The said plows are of course capable of modifications within the S00 e of my invention as herein set forthand c aimed.

-What I claim, and desire to secure by Let ters Patent of the United States, is as follows:

1. The combination with a truck, of a'p'low loosely attached to the truck-frame by a drag connection, and a second loose connection to said plow and to said truck-frame, arranged to permit only lateral and vertical move ments of the low, but to positively hold the same always in an upright position, substantially as described.

2. The combination with a truck and a plow loosely connected thereto, of a bar or rod pivoted to the plow-beam, with freedom for pivotal movements in the vertical plane of said beam, and a pivoted support on the truck-frame, through which the upper end of such bar works telescopically, thereby holdingsaid low in upright position, substan- 3. The combination with a truck and a plow, of a drag connection, attaching said plow to the forward portion of the truck frame, with freedom for vertical and lateral movements, of a device for holding said plow in an upright position, while permitting said movements, said device comprising an upright pedestal swiveled to the truck-frame,- a head pivoted to said pedestal for movements in a vertical plane, and a bar or rod pivoted to the plow-beam, for movements in a vertier end working telescopica'lly through sai pivoted head, substantially as described.

4.. In a gang-plow, the combination with a truck having an approximately triangular truck-frame, a transversely-extended dragbar secured to the forward portion of the truck-frame, a plurality of plows arranged in 'a diagonally laterally spaced row, chains independently connecting said lows to said drag-bars, a fixed shaft on sai truck-frame, overlying said plows and provided with fixed notched disks, levers mounted on saidfixed shaft adjacent to said notched disks and provided with latches cooperating therewith, chains connecting said plows to the overlying lever, and independent devices applied to .said plows and to the truck-frames, for positively holding said plows in upright positions and permitting only lateral and vertical movements of said plows, substantially as described.

In testimonywhereof I afiix my signature in presence of two witnesses.
